Original application led March 3, 1926, Serial No. 91,920. Divided and this application filed August 7,

' 1926. Serial No. 127,831.

This invention is shown in the drawings as embodied in a machinefor vending pencil leads, which is claimed in my prior copending application for-patent filed March 3, 1926, Serial No. 91,920, which fully discloses this invention, and of which this application is a division.

This invention relates more particularly to the enclosing casing. ln carrying out the invention, the vending or purchase-delivering mechanism and the mechanism in theembodiment of the invention shown in the drawings are the same as disclosed in my above noted application, and the coin-controlled mechanism is substantially the same as that disclosed and claimed in my copending application Serial No. 39,442, liled June 25, 1925. 4

An object ,of the invention is toVv obtain increased security of the stock of articles to be vended and of the accumulated coins. Other objects are convenience in use, economy in manufacture, effectiveness, simplicity, strength and durability. Other objects and advantages will hereinafter appear.

According to the invention means are provided to prevent access to one chamber of the casing, such as the coin chamber, until another locked chamber, such as the magazine chamber, has been opened, and to compel the chamber last opened to be closed before the other chamber can be closed for locking it. includes various features of construction and combinations of parts, as will appear from the following description.

rJhe embodiment'of the invention shown f in the accompanying drawings will now be described and thereafter the invention will be pointed out in claims, reference now being had to the drawings, in which:

Fig. l isa vertical section on the zigzag line l-1 of F ig. 2, parts of the operating mechanism appearing in front elevation;

Fig-r2 is a vertical section on the zigzag line2-2 of Fig. l; p F 3 is an enlarged partial vertical section on the zigzag line 3-3 of Fig. 2;

Fig. si is a similarly enlarged horizontal section taken on the line 4-4 of Fig2 and also as viewed from above in Fig. 3'; and

Fig. 5 is al partial substantially vertical section taken on the irregular line 5 5 of 3.

In the vending machine shown in` the coin-controlled The invention as carried out l kand also to include other parts hereinafter described which are formed in one piece therewith. This casing box, together with 4the parts which are to be formed in the same piece therewith, may be a casting, such as a die-casting, of suitable metal such as aluminum. The entire front vof this casing box is originally open. A portion Vof the front .ofthe casing box somewhat below the middle thereof is closed by a transverse wall portion G which is supported, for example, by means of screws 6 from the inside as indicated in Figs. l and 3. This wall 6 is thus supported upon the front and to form a part of a mechanism-supporting frame which includes a rear vertical wall 7 and a lower horizontal wall 8 both of which extend from side to side of the casing box, and this frame may be secured inplace bymeans of screws at the inside of the casing box entering theside walls 2 and 3 thereof as is shown in Figs. l and 2l of the drawings. Thisentire frame may be a die-casting of suitable metal such as zinc.

A lower door 9 is provided below the transverse wall 6 and'atfits lower edge is hinged at 10 to the frontiedge of the bottom casing wall 5 so as to open outwardly and downwardly 'as indicated in dash lines in "Fig: 2. An upper front door' l1 extencs from the upper edge of the transverse wall 6 to the top wall ilv of the casing box and at its lower end has .an undercut interlocking relation with the transversewall 6 sok that For a portion of its width the upper door 11 carries an inner wall 15 which may be secured to the inner ends of the ridges 13 and bosses 14 bymeans of screws as shown in Figs. 1 and 4. This inner wall 15 of the door 11 forms an upward continuation of the frame wall 7 and extends up to the top wall 4 of the casing box where it is notched around a rib 16 shown as formed on and extending from the front to the back of the top casing wall 4. This inner wall forms a front wall and door for the magazine, as will presently more clearly appear, and opens outwardly and is removable with the door 11.

`Interlocking means are provided between the upper door 11 and the lower door 9 so that one of these doors cannot be opened until the other door has been opened, such interlocking` means shown comprising a manually operable locking device which is accessible to be operated only when the upper door 11 is open and which prevents the upper door from being closed unless this device has been operated to lock the lower door. A vertically slidable bar 17, forming a bolt, is guided between the mechanismsupporting frame'and the right side wall 3 of the'casing box by being notched into this frame, as clearly appears in Figs. 1, 2 and 4. The lower end of the bolt 17 engageable in a notch in a keeper or catch 18 provided on and projecting inwardly from the upper portion of the lower door 9 adjacent the casing side wall 3. The upper end portion of the bar 17 forming the bolt is turned over at right angles away from the casing wall 3 to forni a stop 19 to engage the shelf portion 12ZL for limiting the downward movement of the bolt 17 and is thence turned upwardly and then towards the left and slightly inwardly or rearwardly to form a handle portion 2O by which the bolt 17 may be lifted to disengage its lower end from thekeeper 18 and by which it may be restored to its engaging position with this keeper. lVhen thelower end of the bolt 17 is in engagement with the keeper 18, as shown in vfull lines in Figs. 1 and 2, and with the upper door 11 closed, the handle portion 20 of the bolt 17 is received in a notch 21 provided in the adjacent edge of the inner door wall 15 so that the bolt 17 is the door wall 15 will strike this `handle 2O and prevent the upper door 11 from being closed, thereby compelling the bolt 17 iirst to be slid downward to lock the lower door 9, as will be clear from an inspection of Figs. V1, 2 and 4 of the drawings. The upper door 11 is provided on its inner side adjacent to its upper edge with a suitable lock 22 the locking bolt 23 of which is engageable in a recess or notch provided in the rib 1G, which thereby forms a keeper for the bolt 23 as is shown in Fig. 2. The lock 22 may be of any suitable construction and may be locked and unlocked in the usual way by means of a key.

It will now be evident that arcesscannot be had to the interior of the enclosing casing except by first unlocking the upper door 11. Then the upper door 11 has been unlocked and opened then the bolt 17 may be lifted to unlock the lower door 9 which only then can be opened. The vupper door 11 provides access to the upper portion of the enclosing casing for replenishing the magazine while the lower door 9 provides access to the lower portion of the enclosing casing for removing the accumulated coins therefrom. Also when the two doors 9 and 11 have been opened, and only then, the entire'mechanismsupporting frame, together with the mechanism carried thereby may be detached and removed, or replaced. In opening the upper door 11 it is first swung outwardly to substantially the broken line position thereof shown in Fig. 2, after which it may be lifted oil", the upper end of the inner door wall 15 having sufficient clearance to pass the front edge portion of the top wall 4 of the casing box as the door 11 is `swung forwardly.

In order to' obtain a clearer understanding .of the casing construction of the present invention, the coin-moving mechanism employed in carrying `out the invention will now be described as brieiiy as possible. A proper coin may be inserted into the machine through a slightly inclined coin slot 24 in the lower portion Aof the upper front door 11,`as shown in Fig. 3. The inserted coin is received in a coin-holding slot provided in the upper marginal or peripheral portion of a rocking coin .carrier 25. The coin carrier 25 has a pivot stud 26 ournaled in the front casing wall 6 and is similarly pivoted to the wall 7 of the supportingV frame for the operating mechanism. The rocking movement of the coin carrier is limited by stop lugs 27 and 28 provided on the supporting frame to be engaged by a lug 29 which projects from the back of the coin carrier. Wrhen the coin carrier is rocked in a clockwise direction as viewed in Fig. l it will move the coin carried in its'slot through the upper' arc of a circle towards the right and to an oppositely inclined position for thereby operating the purchase-deliverying mechanism, after which it will drop from the slot in the coin carrier upon the rearwardly inclined floor of a coin chute down which it will slide through an opening 30a provided in the frame wall 7 and will drop into the bottom of the casing7 this coin chute being provided on and forming a part of the mechanismsupporting frame as shown in Fig. 1 and as indicated by dotted lines in Fig. 2.

After the coin carrier 25 has been rocked in a forward direction it is automatically retracted by means of a retractile spring 31 which is connected to the lower part of the coin carrier through the intermediary of a feeler lever 32 which forms a feeler for a coin carried by the coin carrier. This feeler lever 32 is pivoted to the lower part of the coin carrier on a pivot pin 33 and on its rearwardly projecting end there are pivoted a pair of reversible pawls 34 which are urged towards a middle position by springs and which when the coin carrier 25 is rocked will wipe over and escape alternately from the opposite ends of an arcuate ratchet 3G provided on the supporting frame.

The coin carrier 25 may be rocked in a forward direction by means of a handle knob 37 having its hub journaled in a bearing sleeve in a boss 38 formed on the front of the casing wall 6. The handle knob 37 is fixed upon the outer end of a handle shaft 39 which passes loosely through a pinion 40 journaled at its ends in the walls 6 and 7. This pinion. engages with an internal arcuate rack formed on the coin carrier as shown in Fig. 1, the handle knob 37 being operatively coupled to the pinion 4() by means of a friction clutch. As the coin held in the coin-h lding slot of the coin carrier is moved by the coin carrier in an arcuate path from the left to the right as viewed in Figs. 1 and 3, between the front wall formed by the upper door 11 and the rear wall 7 forming a part of the mechanism-supporting frame, this coin as it thus moves will oper-v ate the purchase-delivering mechanism, and

supporting frame forms a downward continuation of the vfront wall or door 15 of .the magazine from a point near the lower end of the latter,as is clearly shown in Fig. 2. The lower endk ofthe left side wall 42 of the magazine hopper is provided at its outer or left side with a short arcuate skirt 44.

The top or upper end of the magazine hopper is closedA by thetop wall 4 of the casing box.V The bottom or lower end of the magazine hopper is closed and an arcuate floor or bottom is formed therefor by the upper peripheral portion of a rotatable delivery cylinder 45. The delivery cylinder 45 is fixed -upon a horizontal' drive shaft 46', the rear reduced end of which has a bearing in a boss formed upon the inner `side of the rear casing wall 1 and which at the forward end of the cylinder 45 is journaled in and projects forwardly beyond a boss formed on the forward side of the frame wall 7. The peripheral'surface of the delivery cylinder 45 hasprovided therein a circumferential seriesof longitudinal delivery grooves, of a depth to receive therein one of the pencil leads 41. i

. Strippingfingers 47 are carried by and are shown as formed in one piece with a block 48 which, as shown. i'n Figs. 3 and 4, may be secured by means of screws to a slight lug 49 foimed'upon the adjacent side of the frame wall 7. A chute io'or 50, between the rear casing wall l and the frame wall 7, leads -to the outside of the casing through a slot in the casing wall 2 and terminates at the outside of the easing in a reception trough 5l,y the chute 50 and trough 51 being cast'in the same piece with the casing box. v

A coin-operatedV toothed drive wheel 52 is fixed uponthe ou teiend of the drive shaft 46 in the space between the front casing wall provided by the upper door. 11 and the interior wall 7 providedby the supporting frame. One of the teeth at the lower edge of the drive wheel 52 is normally in thek path of the upper edge portion of a moving coin in position to be engaged thereby and moved a step as the coin is moved by the coin carrier 25 from left to right as viewed in Figs. l and 3. At the completion of a step of rotative movement of the drive wheel 52 the coin carrier 25 will have reached its forward limit of movement and upon the release of the handle knob 37 and the initiation of the return movement of' the coin carrier by its spring 3l, the coin will drop lfrom the coin carrier upon the coin chute 30 and thence to the casing bottom 5. in the drawings parts of the operating InA the casing construction shown `from the frame wall 7.

It will be noted of the casing construction that all parts vof the operating mechanismf are carried by the frame having the front and rear walls 6 and 7, to be removable therewith, such as the handle shaft 39 and the delivery cylinder 45 together with its shaft 46. It should be noted, however, that neither the front wall 6 nor the frame as a whole can be removed without irst un,- locking the lock 22 and opening the doors 9 and l1, so that there is no way by which a part of the casing walls could be removed in order thus to gain unauthorized access to the interior of the casing.

It is Yobvious that various modifications may be made in they construction shown in the drawings and above particularly described, within the lprinciple and scope of the invention as defined in the appended claims.

I claim:

l. An enclosing casing for the magazine and theoperatingl mechanism of a coin-con trolled vending machine comprising a casing box closed against access excepting at one side'thereof, a frame for the operating mechanism having an outer wall forming a transverse wall portion across said one side of the casing box intermediate of its length, means Awithin the casing box for removably securing said frame therein, a manually operable vertically slidable locking bolt guided within the casing Vbor; and extending from the lower part to the upper part thereof, a lower door for the said one side of the casing box below said transverse wall portion, an upper door for the said one side of the casi-ng box above said transverse wall portion, a keeper carried by the lower door in which the lower end of said bolt may be engaged to lock the lower door, a laterally projecting handle portion on the upper end of the locking bolt, a plateearried by the upper door in inwardly spaced relation therefrom and forming a closure for the acent side of the magazine, said plate being engageable with the handle of the locking bolt to prevent the closing of the upper door when the said bolt is ,disengaged Vfrom its keeper on the lower door and said plate having a notch therein to receive said handle when said bolt is in engagement with its keeper thereby to permit 'the upper door to be closed, and a lock for the upper door.

2. The invention defined in claim ll, in which the upper door is removable and is held in place at its lower end by said outer wall oi the frame, and said locking bolt being` guided by said frame to project from` the upper and lower ends thereof and said keeper for the lower door being `below and adjacent to the lower end of said frame.

In witness whereof, I hereunto subscribe my signature.
